Improve Gas Mileage With These Relatively Inexpensive Car Parts

Your vehicle’s efficiency can have a significant effect on your monthly budget. There are many ways to improve overall usage. Owners with do-it-yourself knowledge can replace specific car parts to increase mileage. Even if you don’t know how to replace car parts yourself, you can have a mechanic perform this work for you.

Mass Airflow Sensor

The mass airflow sensor calculates the airflow as it enters the engine. From this point, the sensor passes this information on to the engine’s computer. The engine’s computer is in charge of regulating fuel injection, transmission shifting, and the functions of the ignition system. A clogged mass airflow sensor will result in the engine’s computer receiving inaccurate information, which could negatively impact fuel economy.

Spark Plugs

Spark plugs have the task of igniting a mixture of air and fuel in the engine combustion chamber. Worn spark plugs will not produce an effective ignition. Replacing spark plugs and keeping them clean will provide cleaner and more efficient running of the engine.

Air Filter

Replacing this filter may be one of the most simple, yet effective, ways to improve gas mileage. A soiled and clogged filter will not move air through effectively. The restricted flow to the engine will impact efficiency because the more clean air the engine receives, the better it operates. As you explore these car parts, choose a filter made from fabric instead of paper. You can clean filters made from fabric, so they are reusable. In fact, some of them will even last as long as your car lasts.

Fuel Filter

The fuel filter has the task of moving gas to fuel injectors. A clogged fuel filter will begin moving gas less efficiently, which could lead to increased gas consumption to produce the needed power. Auto manufacturers recommend a specific schedule for replacing this filter. Follow this recommendation to ensure that you maintain the best efficiency of your car.


Tires are an integral component of handling and traction. If you allow tires to wear, become underinflated, or misaligned, you may notice decreased economy. Tires naturally become deflated as you drive your car, so check them once each month to maintain the correct pressure. When you check the tires, look for signs of wear. When replacing tires, choose the narrowest tires possible to cut down on aerodynamic drag. Installing low-rolling-resistance tires may also improve economy slightly.

Fuel Injection Components

Automobiles with fuel injection have sensors and systems that must remain in good condition to ensure the best gas mileage. Have a mechanic check oxygen sensors, evaporative emissions control systems, and the engine emissions system. Faulty sensors and components could result in decreased gas mileage of 20 percent or more.

Many car parts are not expensive, yet they can produce significant improvements in gas mileage when you replace them. Scheduling regular vehicle tune-ups can help to ensure that all auto components function correctly for the best efficiency.

Best Mileage SUV
